FLANGE-ORNL calculates
appropriate loads, stresses, and displacements for the flanges,
bolts, and gaskets that comprise a flanged piping joint for
internal pressure or moment loading on the pipe, temperature
difference between the flange hub and ring, and variations in bolt
load that result from pressure, hub-ring temperature gradient
and/or bolt-ring temperature differences. Flanges considered may
be tapered-hub, straight or blind.

FLANGE-ORNL has a unique set of
user-controlled options which allow for calculating ASME boiler
and pressure vessel code design criteria and/or more extensive
stress analysis, and also for specifying various different flange
design combinations for the joint. In addition, the program
calculates values for various ASME code variables that would
otherwise have to be extracted manually from curves and used as
input.
